There should be plenty of invertebrates for a few adult fish, and plenty of stuff for the fry to feed on as well. This pond is drained yearly to supply water to another below it that is irrigated from so hopefully id be able to net some out when the water gets lower. If I got 20-25 males & females (that are still swollen with eggs)and put them in within the next few weeks, do you think that would be enough for them to spawn? I have zero experience with YP.
